About FlashSnap
FlashSnap uses the Persistent FastResync and Disk Group Split and Join features of Veritas Volume Manager (VxVM).
The FlashSnap snapshot method can be used for alternate client backups only, in the split mirror configuration.
See Alternate client backup split mirror examples.
FlashSnap supports VxVM full-sized instant snapshots, but not space-optimized snapshot. Additionally, FlashSnap supports VxVM volumes in a shared disk group. For support configurations, please refer to the NetBackup 7.x Snapshot Client Compatibility List.
